new catalytic system for single-step alkane synthesis from furans and carboxylic acids was investigated using noble metals-supported red mud (RM) catalysts. Maximum alkane selectivities were 100%, 87%, and 56% over Pt/RM, Pd/RM, and Ru/RM respectively. Potassium doping prolonged the catalyst life by suppressing methanation reaction, decreased coking, and enhancing the stability of noble metals towards
研究了一种使用贵金属负载的赤泥(RM)催化剂从呋喃和羧酸合成单步烷烃的新型催化系统。与Pt / RM,Pd / RM和Ru / RM相比,最大烷烃选择性分别为100%,87%和56%。钾掺杂可通过抑制甲烷化反应,减少焦化并增强贵金属抗氧化的稳定性来延长催化剂寿命。改性催化剂具有五种功能:贵金属上丙酸的部分还原;缓和K上的焦化反应,抑制K上的甲烷化,RM上酸的酮化,以及RM上的缩合加氢脱氧反应。磁铁矿在催化酮化反应中起重要作用。
